Just bought a B&T Forend Quad Rail for my Benelli M4. Everything looked good until I tried to install it.

Apparently, Benelli did some design changes to the barrels on the new M4s so you are now required to remove six threadlocked hex screws to separate the upper rail from the main assembly. I applied about 15 minutes of high heat to lossen the threadlocker, tried and it did not budge. Again applied the heat to try it again. This time stripped the hex screw head.

I did not try the other screws and promptly sent the rail back to DSArms. I asked them if they could remove the upper rail. If they will, I will not request a refund. Anyone else have a similiar problem with this product?
